SMART BIAS TEE – ANT SIDE/TOP OF THE TOWER
The Kaelus SBT0003 provides a flexible Smart Bias Tee solution allowing for AISG and DC to be placed onto a feeder at the bottom of the tower or extracted from the feeder at the top. Operating across all the cellular frequency bands, the SBT0003 provides the following additional benefits.
FEATURES
- 555-3800MHz operation provides coverage in 600MHz through 3.5GHz frequency bands
- Available in top of the tower or bottom of the tower applications
- Primary surge protection limits the voltage let-through from the feeder to the DC port
- Multiple connector configurations to allow for different installation scenarios
- IP67 for continuous outdoor operation
